5.1 General
These assembly instructions enable the owner to fit and/or refit or replace the DC-Com himself. The owner must
appoint a coordinator who is authorized to issue instructions before assembly work commences.
Despite detailed information, mistakes when fitting by the customer cannot be excluded. For this reason, we rec‐
ommend this work be carried out by our trained specialists or by persons authorized by us.
The wiring of the Demag chain hoist complies in all respects with current DIN VDE and accident prevention regu‐
lations.
Unauthorized intervention and modifications result in eliminating compliance with these regulations.
DANGER
Live components
Danger to life and limb.
It must be possible to switch off powerfeed by means of a device for disconnecting the powerfeed (e.g. mains

The chain hoists are supplied with power from an AC power network. The voltage and frequency of the AC power
network must match the data specified on the rating plate of the chain hoist.
